Be it known that I, CHARLES R. Gnoma.

at t.- iaul, in the county of Ramsey and tote of Minnesota, haveinvented certain new" and drytmisg This invention relates to a' launcomposition; and one object 13 to" rovicle a stio of bluing which willdissolve eely and but notdisiniegrste or,

fall away in pal-tic es, and winch will not harden and crack after ithasbeen wet.

In accordance with the present invention the amorphous glassy massWhichresults from melting so a: is employedas a; binder tor the vpowdered Ins, and mostadvanta eously the by the inas granular sugar.

The mixture is most convementl used in the form of sticks, being Ibelieve, moreover, that 1am the first to prepare a comgosition of matterfor anypurpose in which a coloringtherefore in suitably largeproportion, is compounded with said amorphous lassy mass as a binderwith (hr-without a mo material, such as granulareu at. Q I

V In what 18 considered the best mode of proparts "of" granulated daredlrussiarr blue may be and aboiit One-third of lhe sugar is convertedinto the said amorphous. glassy mass, the other two-thirds,orthereabouuremain'mg in a granuls'r state and in such state being mixedwith the amorphous lassy mass 9 35. gradually melted in a heated recstaele and stirred, so that it will liquefyeve y. y I prefer to maintainas near as possible the seine degree of heat around therece taele butnot sum; it to burn'the as r. en tfe or V has t e a pearance ofg aboutonethlrd melted, t e blue can be mixed therew th; but I prefer at thattime-to add first a smell quant'rt of water and then stir in the bluepreferab 7' by adding it in amounts from tune to time until it has allbeen used.

The binding action of said mass is modified bytlienn'melted suganwhich remains xmxed therewith in a-granular state andincreases the solubility of thecomposition. When the composition isrolled into sticks,

as above mentioned and as considered advantageous, such rolling takeslacs while i the mixture is plastic. It so eggently hardenson furthercool The stie may be about half an in h indiarneter or of whatever sizemay; be preferred. V
